What is a Common Noun?
Common Noun Definition: A Common Noun is a general name for any person, place, thing, or idea. It does not refer to something specific. For example, "city," "girl," and "book" are all common nouns because they can mean any city, girl, or book.
Why are Common Nouns Important? They help us talk about things in a general way, making our sentences clear and flexible. Without common nouns, we would have to use specific names for everything!
Function in Grammar
Common nouns are used to name general people, places, things, or ideas. They are the opposite of proper nouns, which name specific people or places. For example:
- Common Noun: city, river, teacher
- Proper Noun: Mumbai, Nile, Mr. Sharma
Common nouns are everywhere in English! They help us talk about the world in a simple, general way.
